Early age onset puberty exposure mature

Recent studies indicate that the onset of puberty is occurring at increasingly younger ages. Many etiologies have been hypothesized to be involved, but environmental exposures are among the most worrisome. This review article summarizes the current understanding of the major environmental influences on pubertal timing, focusing on factors for which the most scientific evidence exists. The research reviewed addresses intrinsic factors unique to each individual , naturally occurring endocrine disruptors and chemical endocrine disruptors. In each category, evidence was found for and against the involvement of specific environmental factors on pubertal timing. The need for research aimed at elucidating the effects of numerous specific yet disparate forms of exposures is emphasized.

One day last year when her daughter, Ainsley, was 9, Tracee Sioux pulled her out of her elementary school in Fort Collins, Colo. Ainsley was the tallest child in her third-grade class. In the back seat, Ainsley wiggled out of her pink parka and looked in her backpack for her Harry Potter book. Over the past three years, Tracee — pretty and well-put-together, wearing a burnt orange blouse that matched her necklace and her bag — had taken Ainsley to see several doctors.

When Is Puberty Too Early?

Precocious puberty is when a child's body begins changing into that of an adult puberty too soon. When puberty begins before age 8 in girls and before age 9 in boys, it is considered precocious puberty. Puberty includes rapid growth of bones and muscles, changes in body shape and size, and development of the body's ability to reproduce. The cause of precocious puberty often can't be found.
